It's much harder to hide flaws if the person is moving around.  
Selfies would be my second choice. Professional photos are a distant 3rd.  

 
One thing that I've never seen done, is a provider actually talking in her videos.  They usually have some sultry soundtrack. I wouldn't mind a little  voice-over.

Selfies, pro shots and videos all play a part and give us gents a different lens, so to speak, to view the provider. The videos I am not crazy about are the ones where it jump cuts from one shot to the next all too quickly. That is frustrating for the viewer.

While edits are obviously necessary, this is a case where less of them is best. I also prefer full body shots, be they pics or vids, rather than super close up shots which give us very little to go on.

...but real vs photoshopped/brushed I'd have to say real is always best.  What I really like is when a provider has an OF or many vids page with b/g videos for two reasons.  I can get a great idea of how she may perform and after seeing her, it's a great perk to subscribe and still enjoy the memories.  

Fwiw, a many vids link will automatically get my attention and cause me to explore OR if I am confident that she's a real provider, I'll chase an OF link as well.  My .02

Now, a link to actual tube site adult work?  Oh yeah!

For me, recent photo updates would suffice for well established ladies like yourself.  
Positive reviews (from established mongers) remains the key factor for me to see new providers ... and no deposits.

I may not be in a place where I want music on.  Kind of like social media videos, sound starts muted and I can turn it on.

I do like the idea of hearing you speak in the video, but obviously wouldn't have sound on if I'm somewhere not completely private.
